Burger tuning n55 jb4
Just installed the BMS jb4 N55, lots more power, have 335 and 135 with BMS jb4, anyone else installed this, curious to review reports...i did not know which cluster setting to use pn the JB4, BMS said that they had not done x1 yet and to try all to see which one looks better, which setting is best, i like stage 2 but used the automatic one and seems to have better power? any help appreciated
